Customer Question

Welcome to JustAnswer.com, my name is ***** ***** I will do my best to assist you. How are you trying to access Zynga.. Do you have the Zynga poker app downloaded? Or are you trying to purchase facebook credit and add it to zynga? Please specify.. And also, when you attempt the purchase from itunes what exactly happens, and what does it say on screen?
